Loading META Prophet model gives a tz, datetime error

[Emile-Reyn]

Good day,

Thank you for the help in advance. I have saved a meta model using

from prophet.serialize import model_to_json, model_from_json

with open('serialized_model.json', 'w') as fout:
    fout.write(model_to_json(m))  # Save model

The model's inputs and outputs are irrelevant.

Then, when trying to load the model using:

with open('serialized_model.json', 'r') as fin:
    m = model_from_json(fin.read())  # Load model

the following error pops up:

ValueError: cannot supply both a tz and a timezone-naive dtype (i.e. datetime64[ns]): Error while type casting for column 'ds'

Any thoughts?
